I'm wondering if there are any general time bands at LHR when the lounges (specifically Galleries lounges in T5) are most most busy? I know that with some other airlines I typically fly, there are predictable times of day when the lounge is packed, and other times when it empties out. Just curious if that's the case with BA at LHR or if it's pretty steady throughout the day.

*If this has already been answered, I would appreciate if someone could point me in the right direction. I have done some searches of this forum but can't seem to find it. Thanks!
